Here's my question, I figured this out using conservation of energy rules, but my first intuition was to solve it uses F=kx since it requires less math. Anyhoo I keep getting a wrong answer using F=kx and I'm assuming I'm doing something stupid:
'A 2kg block is dropped 45cm above a spring. If the spring compresses 5cm, what is the spring constant?':
Why can I not solve this using F=20N, and x=.05m, and plugging in to F=kx ? I think the answer was 8000N/m for those who care
